\fIOperations performed on Cluster table indexes using the NDB API are not visible to MySQL and make the table unusable by a MySQL server\fR\&. If you use this program to drop an index, then try to access the table from an SQL node, an error results, as shown here:

In such a case, your

|
\fIonly\fR
|
|
option for making the table available to MySQL again is to drop the table and re\-create it\&. You can use either the SQL statementDROP TABLE
|
|
or the
|
|
\fBndb_drop_table\fR
|
|
utility (see
|
|
\fBndb_drop_table\fR(1)) to drop the table\&.
